I close this issue because it’s resolved by using "python.languageServer": "Pylance" as the language server. The renaming can be done immediately even in a file with ~3000 lines of Python code.

@MaxFBurg You may have to file this on the language servers depending on which one you are using. If you have Jedi as the language server it uses rope for refactoring. rope is outdated and slow. At this point we are transitioning people from Jedi to JediLSP, so try JediLSP as the language server setting and see if it helps. If you still feel it is slow then please file a bug on https://github.com/davidhalter/jedi

If the language server is Microsoft, this will also be deprecated soon. So replace that with Pylance (you may need to install pylance extension), and see if it helps. If Pylance is slow then please file a bug on https://github.com/microsoft/pylance-release
